Wellington studies increasing rail frequency

BCR = 1.1 for increasing frequency from 30 minutes to 20 minutes between the peaks

It should be noted that at least according to Robert Schwandl these trains have a lot of staff.

Reducing the staff per train would increase the BCR.  You'd think that they could integrate with their smart card, but not in place yet.

I think the system costs of the order of $NZ130m per year to run, so the $NZ22m increase is actually only a small proportion.
